Alot of people have already harped on how op Flesh Sacrifice is, and as insane as that move is, I think Corpse Eater is also op compared to the other races civil talent.

Lets first consider that it is the only talent that actually provides extra narrative unaccesible to every other race. Eating a body part tells a bit of a back story of that individual and helps to better flesh out the world of Divinity through the perspective of the people by letting you look into their memories. This by itself is already better than the "supposedly" 10% cheeper items or the ability to sway a few more conversations in your favor. The fact that it progresses certain quest lines further gives the player an edge when going through the story of the game

If that by itself wasn't already better than the other civil talents, you also get to learn new abilities through Corpse Eater. Infact, you get Adrenaline right at the very beginning, which is universally considered a must have skill on almost every character (eat body part of crime scene victim). From what I've noticed, there's at least 3 free abilities you can get and thats without even getting off the island yet (Btw, they're all pretty damn good). This not only saves money on buying the necessary skill books (no thanks to +1 bartering lol), but also provides a strategic edge in battles as you can better prepare for a fight with more abilities to chose from to keep memorized. Even when you consider the +1 sneak for dwarfs for Guerilla synergy, that fails in comparison to the level of op Corpse Eater provide.

All of this being said, I'd much prefer a buff to the other races civil talents as they are just boring flat stat increases and provide no additional interactions of their own.
